METHOD OF SPACE DISCRIMINATION OF DISTANCE IN SOLVING PROBLEM OF POSITIONING OF MOBILE MEANS BY RHO-RHO FIXING IN SURFACE-MOUNTED LOCAL RADIO NAVIGATION SYSTEM Russian patent published in 2018 - IPC G01S5/04 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and is intended to improve the accuracy of determining the location of mobile means based on the signals of key stations of surface-mounted local radio navigation system (LRNS). This result is achieved due to the fact that the method of space discrimination of distances in solving the problem of positioning of MM by rho-rho fixing in surface-mounted LRNS includes measurement of distances r_i (i = 1, 2, …, n) from the MS with unknown coordinates to the key stations of the LRNS with known coordinates P_i, i = 1, 2, …, n, filtration of measured distances in median filters, calculating the errors between the original distances and their evaluation after filtering, and then transmitting the received errors to the selection control unit for calculating the greatest error and formation of key’s control command to turn off the line, preventing the transmission of estimates of distances with the greatest errors to the MM coordinate calculation unit.

EFFECT: technical result is high accuracy of locating a mobile means (MM).
